Eccentric crank slider umbrella-type external claw

Abstract

The invention discloses an eccentric crank slider umbrella-type external claw, which comprises a telescopic mechanism and an umbrella-type external claw, wherein the telescopic mechanism comprises aninternal cylinder and an external cylinder in mutual sleeving connection and capable of sliding relatively along the axial direction, the internal cylinder is inserted to the center through hole of the external cylinder, and the top parts of the internal cylinder and the external cylinder are provided with entrances for enabling oranges to fall; the umbrella-type external claw for picking orangesis assembled between the top of the internal cylinder and the top of the external cylinder; opening and closing of the umbrella-type external claw are controlled through relative sliding between the internal cylinder and the external cylinder; the umbrella-type external claw comprises a plurality of arc clamping claws and connecting rods for controlling the arc clamping claws to swing vertically;the arc clamping claws are arranged on the periphery of the telescopic mechanism and the bottom ends of the arc clamping claws are hinged on the internal cylinder; and one end of the connecting rod ishinged on the external cylinder and the other end is hinged on the arc clamping claw. The eccentric crank slider umbrella-type external claw has the beneficial effects that a mechanical arm can easily extend into the branches and locate the position of a fruit quickly without damaging the fruit; the umbrella-type external claw can push the branches aside, and interference of leaves is reduced when a petiole is cut; and the structure of the mechanical arm and the fruit can be protected.

Description

technical field [0001] The invention relates to an umbrella-shaped outer claw of an eccentric crank slider. Background technique [0002] At present, there are few similar picking mechanical devices including other fruits on the market, and the requirements for picking low process planning are also high. Moreover, it is necessary to climb a ladder for picking high places, which has certain safety hazards, so it is necessary to use fruit picking robotic arms. But the fruit picking arm head on the market only has simple cutting and collecting mechanism now, causes fruit damage easily. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention proposes a method that enables the mechanical arm to more easily extend between the branches, and quickly locate the position of the fruit without damaging the fruit. At the same time, the umbrella-shaped outer claw can push away the branches and reduce the interference of leaves when cutt...
